** Module:	Case_Item
** Description:	This module implements the Case_Item abstraction.  A
**	case item represents a single branch in a case statement; it
**	thus consists of a list of labels and a statement to execute
**	when one of the labels matches the selector.
** Constants:
**	CASE_ITEM_NULL	- the null item
